JOSEPH J SOHOLFIELD, OF PROVIDENCE, RI-IODE ISLAND.

CLOTH-GUIDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 593,550, dated November 9, 1897.

Application filed August '7, 1891. Serial No. 402,038. I (ModeL) To all whom it may concern.-

Be it known that I, J OSEPH J. SCHOLFIELD, of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Cloth-Guiding Machines, of which the following is a specification.

My invention consists in the improved combination of parts whereby the machine is made simple in its construction and efficient in operation, as hereinafter fully set forth.

Figure 1 represents a top view of a machine embodying my improvement. Fig. 2 represents a side view with one of the web-guides broken away. Fig. 3 represents a rear end view of the machine. Fig. 4 represents a forward end view. Fig. 5 represents a detail section of the guide-roller and its support. Fig. 6 is a detail sectional view showing a modification.

In the accompanying drawings, A represents the frame or stand, to which are attached the stationary forwardly projecting webguides B B, and upon the spindle O, which is journaled in the hub a of the stand and supported at its inner end by the arm D, are placed one or more inclined guide-rollers b b, which are set at an inclination with the axis of the spindle C, so that the rotary movement of the spindle C will cause a change in the angle of the axis of the guide-roller with the plane of the edge of the running web E, as indicated by the dotted line in Fig. 1. The detector F is provided at its engaging edge with the beveled teeth 0 c or a roughened surface and is held upon the inner end of the spindle G, at the outer end of which is secured the gear H, which engages with the intermediate gear I upon the stud J, the said gear I engaging with the gear ,K upon the outer end of the roller-supporting spindle C, so that the angular movement of the detector F in one direction will serve to impart movement to the spindle Olin the same direction, so that the engaging surface of the detector and the adjacent surface of the spindle C will move in opposite directions, and the loose roller L is provided in order to prevent undue friction caused by the pressure of the web between the oppositely-moving surfaces of the detector and the spindle C.

When the cloth is threaded through the machine, as shown by the dotted line E in Fig. 4, passing under the web-guides B at each side of the guide-roller, the friction of the web upon the surface 61 of the disks 1' between the guide-rollers b b, or the friction of the said rollers against the shoulders g, will cause the turning of the spindle C until the pin e strikes against the side of the stop-pin f, as shown by the dotted lines in Fig. 4, and in this case the detector F will be in the position represented by the dotted lines; but as soon as the edge of the web has been carried by the action of the inclined guide-rollers b 5 into engagement with the teeth 0 c of the detector F the resulting movement of the detector F by the forward movement of the edge of the web which is now in engagement with the said detector will cause the reverse movement of the roller-supporting spindle C, so that the pin 6 will strike against the stoppin f, as shown in Fig. 4, the inclination of the guide-rollers b b with the axis of the supporting-spindle being in this case as is represented in Fig. 1, by means'of which the edge of the web will be carried away from contact with the detector F, whereupon the pin E will be again turned to contact with the pin f and the edge of the web be consequently brought back to the detector F, as before.

In order to turn the roller-supporting spindle C in the direction of the moving web with greater facility, a light coiled spring It may be arranged upon the stud J, as shown in Fig. 3, to actuate the intermediate gear and thence the roller-supporting spindle,

- The guide-rollers b b may be held in their inclined position with relation to the axis of the spindle O by means of the disks t', which are provided with a hub j, upon which the guide-rollers are placed, and with an inclined perforation is, adapted to fit the spindle, the said disks being held in line and prevented from turning upon the spindle by means of the inclined face m of the wedge-shaped collar n, which is tight upon the spindle, and the correspondingly-inclined face of the head 0, which is attached to the spindle O by means of the pin 19, so that, while the disk 1' partakes of the rotary movement of the spindle O, the several guide-rollers b b are loose and rotate each upon its own axis, which is inclined to the axis ofthe spindle O but in carrying out my inventiona single inclined roller may be employed instead of the series of rollers shown in Figs. 1 and 2'as, for instance, the single guide-roller b,imm ediately adjoining the fixed collar n, as shown in Fig. 6.

I claim as my invention 1. The combination of the supporting-spindle, and a stop for limiting the rotary movement of the same, and a guide-roller supported upon the spindle at an angle with the axis of the spindle, with the detector geared with the spindle so that the angular movement of the detector in one direction, will impart a corresponding movement to the spindle in the same direction, substantially as described.

2. The combination with an angularly-set guide-roller, the supporting-spindle therefor, and the spring for actuating the supportingspindle in one direction, of the detector arranged in positive connection with the supporting-spindle, whereby the movement of the detector by the engagement of the edge against the resilience of the spring, substan-- tially as described. a

3. The combination of the supporting-spin-- dle, and a stop for limiting the rotary movement of the same, and a guide-roller sup-' ported upon the spindle at an angle with the axis of the spindle, with the detector geared with the spindle, so that the angular movement of the detector in one direction will serve to impart a corresponding movement to the spindle in the same direction, and the antifriction-roller interposed between the adj acent surfaces of the spindle and the detector, substantially as described.
